Description
Technical Field
The utility model belongs to the technical field of calibration equipment technique and specifically relates to a laser light path calibrating device.
Background
Since the advent of laser, it has been popular with people for its excellent performance, and is widely used in various fields such as industry, medical care, communications, military, and scientific research. With the development of laser technology, the variety and function of laser are becoming diversified to meet the demands of different industries.
The laser resonant cavity is the most basic component of the laser, the resonant cavity system mainly comprises a total reflection mirror, a working medium and an output mirror, and in order to fully utilize the internal space of the laser, increase the cavity length and control the volume of the resonant cavity, a plurality of folding cavity mirrors can be inserted into the cavity to turn back the light path in the cavity to form a folding resonant cavity, such as an L-shaped or U-shaped resonant cavity. Because the number of elements in the cavity of the folded resonant cavity is large, if the elements have positioning errors, the optical path of the resonant cavity can be influenced greatly, and the performance of the laser is directly influenced.
Therefore, fast and accurate tuning of the laser cavity is the first step, and the most fundamental and critical step, for the laser.
In the adjusting process of the traditional laser resonant cavity, the most widely adopted method is to use a helium-neon laser as collimation indicating light to adjust the position of each cavity mirror in the resonant cavity. However, in the case of a folded resonator, there is a difficulty in using a general pilot light adjustment. If 2 pieces of 45-degree reflectors are used in the U-shaped resonant cavity to vertically deflect the light path, if a beam of indicating light is used for adjustment independently, the loss of the reflecting surface to the indicating light is extremely large, the reflected light is extremely weak when the cavity mirror is installed, the accurate pointing of the reflected light is difficult to judge, and the installation and adjustment difficulty is increased.
And the laser display card is covered above the light receiving cavity mirror to display the spot range, but once the display range is exceeded, the spot is difficult to find. The laser display card with large size is easy to shield the light receiving cavity mirror, thereby losing the position of the light receiving cavity mirror. Therefore, the light path adjustment is time-consuming and low in efficiency all depending on the proficiency of an operator, and particularly, the light path adjustment is more difficult because the resonant cavity adopts a complex folding cavity.
In addition, for example, in laser cutting, a flying type optical path system is used, and the laser optical path is deviated in long-term use and greatly affects cutting, so that it is necessary to periodically check the optical path and adjust the optical path.
